It is linked to the University of Torino Medical School. Its mission is a significant contribution to fight cancer, by understanding the basics, and by providing state-of-the-art diagnostic and therapeutic services. At the core of the Institute is the interface between molecular biology and medicine. The FPRC provides enduring fund raising to complete and develop the Institute’s buildings and technologies to foster research. CANDIOLO CANCER INSTITUTE About Us | 5 6 | The Link with the University of Torino THE LINK WITH THE UNIVERSITY OF TORINO Since its founding, The Candiolo Cancer Institute has been linked to the University of Torino by formal agreements, the first one contracted in 1994, two years before the completion of the buildings. The cooperation between the Institute and the University was renewed and implemented by a series of agreements signed in the 2002 and in the 2011, to share scientific programs of advanced oncological research. To date, in the Institute operates a branch of the Department of Oncology, born in 2012, and host a number of investigators scattered among other department of the University or the Politecnico of Turin. The University Department of Oncology gathers academic competences in the field of Cancer research, both basic and clinical. The Department belongs to the School of Medicine and its personnel has teaching responsibilities in academic courses. Students and graduates (PhD and MD) are offered specialized and meticulous formative programs, in a multidisciplinary environment in house, at pre- and post-doctoral level, aimed at the underpinning of creative, independent and productive researchers in the cancer field. Embedded in the Candiolo Cancer Institute, the University of Torino has 19 full or associate professors, 8 technicians, 3 clerks and 66 young researchers, working full-time. The Link with the University of Torino | 7 8 | Mission MISSION Candiolo Cancer Institute is a biomedical and clinical research center entirely devoted to the study and the treatment of cancer. Its mission is to transfer experimental preclinical information into clinical practice, through the continuous flow of knowledge from the fields of genetics, molecular and cell biology, pathology. The Institute aims to offer a significant contribution to the defeat of the disease through scientific research and clinical practice of excellence. In order to fulfill these goals, the Institute: (i) capitalizes on knowledge by conducting scientific research in oncology and – at the same time – promoting a fast transfer of knowledge to the clinical practice; (ii) provides assistance in cancer prevention, including the identification of genetic risk factors; (iii) performs diagnostic studies, using state-of-the-art instrumentation and technology; (iv) provides a full cycle of treatment on the premises, employing -besides the best conventional therapies– protocols for novel targeted therapies and clinical trials for ‘precision medicine’. Focus Basic and clinical research makes the Institute of Candiolo a center of excellence focussed in the study, prevention and treatment of the dreadful complication of cancer, metastasis. Basic Research The current knowledge about the mechanisms of cancer onset and progression is provided by basic disciplines, such as genetics, cell and developmental biology. Thanks to these studies, it is possible to classify tumors not only on the basis of their site of origin and histopathological features, but , notably, by the identification of the genetic lesion(s) that support their growth. The tasks of the Institute basic research are aimed at understanding the mechanisms that control normal cell functions responsible for proliferation, and at analyzing how these mechanisms are corrupted during neoplastic transformation. The topics include signal transduction, DNA duplication, cell division, differentiation, senescence, apoptosis and cell motility. Recent studies suggest that anti-neoplastic therapy is really effective not only when it hits the appropriate molecular target (vide infra), but especially when hits the cells feeding the tumor mass. Indeed, most of the cells of the neoplastic mass are quite innocuous and can be attacked with classic therapies, while only a small fraction of them are resistant to treatment and able to regenerate the tumor. This small subpopulation includes the “cancer stem cells” – strictly related to normal “stem cells” – which control the development of our organism during embryonic life and allow us to renew the worn parts in adult life. The up-to-date conceptualization of Cancer defines it as a “somatic, genetic disease of the stem cells”. Translational Research (ECMO: Experimental Clinical Molecular Oncology) Translational research is the “heart” of the Institute, bridging the gap between basic and clinical research. Based on recent technological advances, genomic analysis makes possible –in a significant percentage of cases– the identification of genetic alteration(s) with a “driver” role in tumor development. However, the contribution of each lesion to the transformed phenotype remains elusive. Moreover, knowledge is still insufficient about the mechanisms that control the lack of response to targeted therapies, even in the presence of the molecular target (primary resistance), as well as on the mechanisms that lead to progressive attenuation of the response after prolonged treatment (acquired resistance). Mission| 9 ECMO research aims at the fulfillment of some ambitious Goals to integrate the traditional prognostic and diagnostic factors with a detailed characterization of the genetic and functional alterations of the tumor; to identify new malfunctioning regulatory pathways in cancer; to isolate and study the cancer stem cells; to develop new preclinical platforms that can reliably disclose –and understand in detail– the prospective results of clinical practice. The generation of this kind of knowledge is necessary to designt clinical trials that will be no longer based on empirical observations but on a strong rational. Investigational Clinical Oncology (INCO) Cancer is a complex disease, tied to genetic lesions, that increase in number over time, as a consequence of genetic instability and exposure to environmental carcinogens. Thus, a cell clone proliferates and invades the adjacent tissues in uncontrolled way. Since cancer cells contain several genetic anomalies, and tend to accumulate more anomalies as time passes, cancer is a heterogeneous and hard-to-attack disease, just because it would be necessary to aim at many targets that continuously change. The molecular lesions that cause and sustain the most tumors are, however, finite in number (the bona fide oncogenes). These findings drove clinical pharmacology to commit to an epochal effort to create drugs, called “targeted”, able to contrast the function of specific oncogenes. The strategy of the Institute at Candiolo intends to make significant contributions to the field of cancer targeted therapy by: (i) identifying pathologies and recruiting patients sensitive to the therapies currently in use; (ii) planning and performing –in international networks – the related clinical trials; (iii) developing translational and preclinical research aimed at designing new targeted therapies, if not available yet. Molecular diagnosis and “personalized” medicine The success of targeted therapies is based on the rationale that the target molecule is ‘druggable’ –as a consequence of the genetic anomaly– in the tumor but not in the healthy tissue, and therefore its deactivation has consequences restricted to the neoplastic mass, with a minimum of ‘off-target’ consequences, leading to generic organ damage. This notion has two important clinical outcomes: first of all, before treating patients with a given targeted therapy, it is necessary to verify the presence of the genetic lesion “predictive” of the sensitivity to the drug. Second –in the perspective of targeted therapies– the tumors will be classified not only according to their site of origin and/or morphological features, but also on the molecular lesion(s) which earmarks them and, at the same time, makes them vulnerable to a targeted treatment. Therefore, new therapies are not only “targeted” but also “personalized”. This new approach is called “precision medicine”. Clinical Research At the Institute, oncologists, surgeons and radiotherapists cooperate with scientists to design clinical trials based on molecular data, intended to verify hypotheses and generate novel ones. In order to make this cooperation productive, the Institute manages a daily net of interactions involving formal aspects (seminars and meetings), training (refresher courses and lessons), operational efforts (contacts with the pharmaceutical companies, and management of regulatory instruments). Clinical Research is the last and more direct haven to improve the assistance to cancer patients, providing them with the most appropriate, novel, safe and effective therapeutic approach, according to the genetic characteristic of their own tumor , as an ultimate means to increase their life expectancy.

The current knowledge on mechanisms of cancer onset and progression has been provided by basic disciplines, such as cell biology, developmental biology and genetics. The tasks of Research Topic 1 are aimed at understanding the mechanisms controlling the normal cell functions responsible for the regulation of cell proliferation and at analyzing how these mechanisms are corrupted during neoplastic transformation. The topics include signal transduction, DNA duplication and cell division processes, differentiation, senescence, apoptosis and cell invasion. Special attention is given to the microenvironment and to the relations of the neoplastic cell with the adjacent cells. In the past, the angiogenic process and the vascularization of the tumor mass have been studied in detail. Research Topic 1 is focussed on: 1.1 The role of Semaphorines in invasiveness, metastases and angiogenesis 1.2 The plasma membrane in metastases dissemination 1.3 Tumor angiogenesis MET gene amplification and MET Protein overexpression in a Human gastric carcinoma The mechanisms of cancer onset and progression | 13 Semaphorins: structure & functions Luca Tamagnone MD Laboratory of Cancer Cell Biology [email protected] Rationale Study of the molecular mechanisms that regulate tumor invasion and metastatic dissemination, with focus on the signals mediated by Semaphorins, acting in tumor cells and in cells of the tumor microenvironment. Results In preclinical murine models, semaphorin 3E/Plexin D1 signaling pathways drive the metastatic dissemination. Furthermore, the expression of Sema3E in primary human colorectal tumors correlates with the formation of distant metastases. This suggests that the expression of semaphorin 3E/Plexin D1 in human tumors represents an independent prognostic factor for patients stratification. Furthermore, in preclinical models in vivo, this signaling pathway driving tumor progression can be blocked by a modified variant of Sema3E (UNCL-Sema3E). This molecule shows strong anti-angiogenic and anti- metastatic activities. Finally, the receptor Neuropilin-1 controls the signaling pathway mediated by EGFR, a major oncogene driving tumor progression, targeted by innovative therapeutic approaches. The elucidation of the functional role and molecular mechanisms by which Semaphorin genes control the invasiveness of tumor cells and the formation of metastases will prompt the development of innovative diagnostic and therapeutic approaches.

Invest. 2009, 119:3356-72 Guido Serini MD PhD Laboratory of Cell Adhesion Dynamics [email protected] Rationale The binding of cells to the surrounding extracellular matrix is mediated by a class of adhesive receptors known as integrins, which can assume active or inactive conformations, respectively characterized by high or low affinity binding to the extracellular matrix. Results We showed how the modulation of integrin conformation and traffic is a key aspect of the molecular signals through which semaphorins control via their receptors plexins the correct morphogenesis of the vascular system; an abnormal control of these signals underpins the alterations that characterize tumor blood vessels. Finally, we found out how restoring the physiological inhibitory control of integrins by semaphorin can effectively prevent such vascular abnormalities, thus improving blood supply and penetration of anti -neoplastic as well as counteracting metastatic dissemination. Projects and goals Characterization of the mechanisms and molecular determinants responsible for: (i) inhibition of the adhesive function of endothelial cells by the secreted semaphorins; (ii) the selective control of active integrin traffic in endothelial cells. Molecular variants of semaphorin endowed with greater affinity for the receptor will be generated by mutagenesis and their potential therapeutic efficacy will be experimentally tested in transgenic models of cancer.

Sema3A re-expression by somatic gene transfer into different tumor types, significantly impaired angiogenesis, blocked tumor growth and metastasis formation, by normalizing the vasculature and inhibiting cancer hypoxia. Recently we demonstrated that the treatment of several mouse models of cancer with Sema3A, by inducing tumor blood vessel normalization and improving cancer tissue oxygenation, efficiently overcame the evasive resistance to the anti-angiogenic therapy induced by clinically approved drugs, such as Sunitinib and DC101, blocking metastasis and enhancing the survival. Moreover, Sema3A, improving vessel perfusion, significantly improved the delivery of chemotherapeutic drugs to the tumors and enhanced their efficacy. Projects and goals (i) to employ Sema3A super-agonists mutants as new compounds to overcome the evasive resistance to the anti-angiogenic therapies, to halt metastasis formation and to normalize tumor vessels; (ii) to assess the efficacy of combining Sema3s or other axon guidance cues delivery with conventional anti-angiogenic drugs to block metastases dissemination using different mouse models of cancer; (iii) to identify the mechanisms by which Semas, their receptors and other axon guidance cues regulate “stroma” normalization, tumor invasiveness and metastases formation. Team Federica Maione, Stefania Capano, Donatella Regano 16 | The mechanisms of cancer onset and progression The better understanding of the anti-metastatic and normalizing effects of Sema3s on tumor blood vessels, will allow to design new strategy to overcome the resistance to the anti-angiogenic therapy.

Proc Natl Acad Sci U S A. 2011, 108:17337-42 Letizia Lanzetti PhD Laboratory of Membrane Trafficking [email protected] Rationale Metastatic cancer cells, in order to spread, must activate a process known as invasive growth. The invasive growth program relies on the activation of plasma membrane receptors that are essential for proliferation and migration of metastatic cells in the surrounding tissues. Among these receptors, a key role is played by the family of adhesive receptors integrins and by the tyrosine kinase receptor Met. Several molecules finely regulate their activation and localization to the plasma membrane. Our unit studies some of these proteins, such as the small GTPase Rab5 and its effectors, whose function is to control the endocytosis of the receptors, their removal from the cell surface, and their downregulation. Results (i) We have isolated a novel regulator of growth factor-mediated cell migration. This molecule, named USP6NL, by turning off the GTPase Rab5, inhibits the endocytosis of adhesive receptors strongly reducing cell motility; ( ii ) we have also identified a novel function of Rab5 in the correct segregation of chromosomes during cell division . Projects and goals (i) To identify the molecular mechanisms that control the traffic of integrins and of the Met receptor in cancer cells characterized by increasing degrees of invasiveness; (ii) to study the effects caused by antibodies and catalytic inhibitors in the endocytosis and downregulation of tyrosine kinase receptors; (iii) to characterize the role of Rab5 and of its molecular network during the division of normal and cancer cells.

The mechanisms of cancer onset and progression | 17 From neuronal biology to neoplastic progression Marco Arese PhD Laboratory of Neurovascular Biology [email protected] Rationale We want to exploit the presence of proteins of nervous origin in the “integrated” tumor tissue, and all the relative knowledge deriving from the field of neurobiology, to bring new therapeutic tools in oncology. Neurexin and Neuroligin, two neuronal synaptic proteins, are the main objectives. Results Neurexin and Neuroligin are produced not only by neurons but also by cells of the vascular system, and they promote the formation of new blood vessels in experimental models of embryonic development and tumor angiogenesis. We generated a monoclonal antibody against an isoform of Neurexin that inhibits angiogenesis. Functionally, Neurexin and Neuroligin cooperate with VEGFA, the most studied pro-angiogenic factor, and with the adhesive receptor integrin alpha 6 beta 1, an important mediator of tumor angiogenesis. We also showed that Neurexin and Neuroligin are produced by tumor cells and that the expression of Neuroligin is strongly reduced during colorectal cancer ( CRC) progression. The reconstitution of its expression in CRC cells restricts the growth of the tumor. These data support the hypothesis that Neuroligin acts as a tumor suppressor in CRC. The identification of ‘molecular keys’ that mediate the relationship between tumor cells, blood vessels and nerves will contribute to the definition of a new class of therapeutic targets.

EMBO Mol Med. 2012,4:1156-75 Federico Bussolino MD Laboratory of Vascular Oncology [email protected] Rationale Tumor angiogenesis is a validated target to fight solid tumor. However, clinical results are far from the expectations coming from animal models that clearly demonstrated that the inhibition of VEGF pathway halts tumor progression. In this context our main goal is to study the circuits between cancer and vascular cells to obtain new knowledge useful for envisaging the therapeutic approaches. Results (i) PLX4720, a specific inhibitor of the mutated kinase BRAFV600E, promotes vascular normalization and disease stabilization in preclinical models of colorectal cancers and melanomas; (ii) during embryo development VEGFR2 expression and activity is regulated by membrane proteins, including Neuropilin-1 and integrins and a specific co-regulatory mechanism occurring in embryonic stem cells drives the differentiation towards vascular or neural cell compartment; (iii) by combining bioinformatics and “gene-silencing”based approaches we identified Tfeb, as a key transcription factor involved in epithelial-mesenchymal and in endothelial-mesenchymal transitions; (iv) VEGFR2 and Tie-2, which is the receptor for angiopoietins, form different complexes with integrins, which modulate the temporal and spatial signalling responses. Projects and goals (i) To study the circuits between stroma and cancer cells in 3D cultures (ii) to analyse tumour growth in mouse models carrying fibroblasts or endothelial cells genetically modified; (iii) to analyse by systems biological techniques of VEGF network, to identify new druggable targets ; (iv) to analyse the transcriptome of stroma and vascular cells isolated from cancer tissues, which do not respond to anti-angiogenic; (v) to identify of the methylome in models of resistance to anti-angiogenic therapies; (vi) to study the role of mixed regulatory circuits between transcription factors, microRNAs and long-non coding RNAs in tumour.

Cancer cells spread from the initial site of tumour growth acquiring an invasive phenotype characterized by both the loss of cell-cell interactions and increased cell motility. Vascular cells migrate into tumor mass forming new vessels in a process called tumor angiogenesis. Results We demonstrated that PDK1, the pivotal molecule in the PI3K signalling pathway, was necessary for endothelial and breast cancer cell migration. Now we are characterizing the pathway linking PI3K/PDK1 to the actin cytoskeleton, integrins and contraction, and how these pathways regulate motility in carcinoma and endothelial cells. We showed that integrin alpha6 is upregulated during tumor angiogenesis and it was involved in the endothelial sprouting process. We developed new three-dimensional culture systems that in combination with conventional cell biology approaches, allow studying collective and directional cell migration. The identification of molecular mechanisms involved in tumor cell migration will allow to prevent the metastatic dissemination by pharmacologic inhibition.

Serena Marchiò PhD Laboratory of Cancer Microenvironment [email protected] Rationale While much is known about the biology of the cancer cell as an autonomous entity, the molecular network that drives the crosstalk between tumor cells and the host tissue remains a largely unexplored area. In particular, in metastatic colorectal cancer these interactions play a key role in the early development stages of the disease. Results Two adhesion molecules, i.e. E-cadherin and a6 integrin, have been identified as a new receptor complex expressed on the surface of cells of metastatic colorectal cancer (CRC). This receptor binds specifically to a soluble protein produced by the healthy liver, the angiopoietin-like factor 6, driving the recognition between the two tissues in the steps of homing, engraftment and colonization. The activation of this molecular circuitry also leads to the induction of a transcriptional program that provides cancer cells with stem cell features (block of differentiation, motility, alteration of proliferative and morphological parameters), thus increasing their metastatic potential. Projects and goals To provide the ‘signature’ of other extracellular proteins that drive cell-cell and cell-matrix interactions in the microenvironment of metastatic CRC. This ‘signature’ will be exploited to identify protein markers useful for the development of diagnostic tools. Such markers, at the same time, may represent potential targets for new biological therapies, particularly where the presence of specific mutations makes patients non-responsive to current treatment regimens. Team Alice Bartolini The mechanisms of cancer onset and progression | 21 Mechanisms of escape from anti-angiogenic therapy Paolo Michieli PhD Laboratory of Cancer Metabolism [email protected] Rationale Anti-angiogenic therapy is one of the most utilized biological therapies for the treatment of metastatic colorectal carcinoma. Despite the initial enthusiasm clinical trials have shown that anti-angiogenic agents are less effective than anticipated. The fundamental biologic problem behind these clinical observations resides in the resilience of tumor cells, which know how rapidly adapt to unfavorable environmental conditions. Hypoxia and glucose or amino acid deprivation themselves may induce an adaptive response driving cancer cells to become more aggressive and metastatic. Results A previous study dentified the HGF/MET pathway as an important regulator of cellular invasiveness in response to hypoxia. Based on this study, we hypothesized that this molecular mechanism may be responsible for invasive resistance to anti-angiogenic therapy of colorectal carcinoma. In a number of orthotopic mouse models of colorectal cancer we show that: (i) treatment with angiogenesis inhibitors cause activation of the HGF/MET pathway in the tumor; (ii) in the presence of HGF, angiogenesis inhibitors lose their efficacy and induce the formation of metastases; (iii) treatment with HGF/MET inhibitors increase tumor sensitivity to anti-angiogenic therapy and prevents the occurrence of metastases consequent to angiogenesis inhibition. Projects and goals While much emphasis has been put on the consequences of tumor hypoxia, little relevance has been attributed to the role of nutrient deprivation. Ongoing experiments indicate instead that sugar and amino acid metabolism plays a relevant role in determining response or resistance to anti-tumor therapies, and in particular to anti-angiogenic therapy. The research will focus onto gaining new insights into these biochemical pathways in preclinical models, investigating the link between oncogene signal transduction pathways and metabolism on one hand, and the effect of anti-metabolic drugs on tumor growth and invasion on the other.

Research topic 2 From Molecular Biology to “Precision Medicine” Research topic 2 is the scientific core on which the projects of most laboratories of the Institute are focused. Advances in genome sequencing and expression analysis has made possible to quickly identify genetic alterations with a potential “driverl” role in tumor development, with an unprecedented informative power. Thanks to these studies, today it is possible to classify tumors, not only on the basis of their site of origin and histopathological features, but also – and especially – by the identification of the genetic lesions that support their growth and that, for this reason, provoke tumor death when deactivated by targeted therapies. However, the contribution of each lesion to the transformed phenotype remains elusive. Moreover, knowledge is still insufficient on the mechanisms that control the lack of response to targeted therapies, even in the presence of a molecular target (primary resistance), as well as on the mechanisms that lead to progressive attenuation of the response after a prolonged treatment (acquired resistance). Translational Research is a multi-disciplinary task based on the expertise of a new generation of scientists, specifically trained to translate molecular information into more effective treatments. The goals are ambitious: to integrate the traditional prognostic and diagnostic factors with a very detailed characterization of the genetic and functional alterations of the tumor; to identify new malfunctioning regulatory pathways in cancer; to isolate and study the cancer stem cells; to develop new preclinical platforms that can reliably disclose – and understand in detail – the prospective results of clinical practice. The generation of this kind of knowledge is instrumental to instructing clinical trials that will be no longer based on empirical information but on a strong rational connotation.

Paolo Comoglio MD Laboratory of Exploratory Research [email protected] Rationale Growing evidence prompted us to hypothesize that the metastatic process involves members of the gene ‘super-family’ of tyrosine kinase receptors for ‘scatter factor’, homologues to Met oncogene (Ron, Axl, Mer and Tyro). Recently, other poorly characterized genes of the family have been identified, Ror1 and Ror2, that can possibly interfere with the response to drugs directed against Met (entered in the clinic), generating resistance. Results In the past we have shown that the Met oncogene encodes the receptor for the ‘scatter factor’ HGF. A series of studies –performed for two decades in this and other laboratories- revealed the involvement and the importance of this oncogene in human cancers, demonstrating its key role in the control of ‘invasive growth’, a genetic program driving the metastatic process. We contributed to the development of drugs inactivating the Met tyrosine kinase: either chemical inhibitors or monoclonal antibodies. These drugs inactivate cancer stem cells in preclinical models of glioblastoma, colorectal and gastric carcinomas, and provides promising results in clinical trials. Projects and goals We are now working on the characterization of tyrosine kinase receptors of the Met oncogene family (Ron, Axl, Mer and Tyro, Ror1-2) at genetic, biochemical and functional level. In particular, we are studying their possible interference -positive or negative- with the intracellular signaling triggered by Met during the execution of the invasive growth program. Emphasis is given to the study of an hyper-metastatic syndrome, the so-called CUP, metastatic cancer from unknown primary origin. Team Cristina Basilico, Silvia Benvenuti, Alessandra Gentile, Maria Rita Virzì Mechanisms underlying down-regulation and ‘shedding’.of the Met oncogenic receptor upon binding of a specific therapeutic antibody From Molecular Biology to “Precision Medicine” | 25 Preclinical models of oncogene ‘addiction’ Livio Trusolino MD Laboratory of Precision Medicine [email protected] Rationale It has now become increasingly clear that some tumors are dependent on one ‘dominant’ genetic lesion for their relentless growth and survival, so that therapeutic inactivation of this lesion results in tumor regression (‘oncogene addiction’). However, this acquired knowledge has been translated into effective treatments very slowly, in part due to difficulty in predicting how the complex mutational background of human cancers can influence the activity of the dominant oncogene, thus modifying response to therapies. Results In the past years we have identified ‘private’ signaling partners of the Met tyrosine kinase, which are able to fine-tune ‘public’ signaling outputs and to confer signal specificity to Met-triggered transduction pathways. We have also introduced the concept of ‘oncogene expedience’, as opposed to ‘oncogene addiction’, to explain tumor contexts in which Met acts as an adjuvant prometastatic gene rather than as a genetic determinant of the transformed phenotype. Finally, we have demonstrated that patient-derived xenografts from metastatic colorectal carcinomas (‘xenopatients’) reliably mimic disease response in humans and prospectively recapitulate biomarker-based case stratification. By this approach, we have identified the HER2 oncogene as a predictor of resistance to anti-EGFR antibodies and as a predictor of response to combinatorial therapies against HER2 and EGFR in this tumor setting. In the same vein, we have recently found that amplification of the MET oncogene correlates with resistance to anti-EGFR therapies and is an effective therapeutic target in KRAS wild-type colorectal tumors. Projects and goals Our projects aim at exploring the mechanisms that underlie tumor addiction to defined genetic lesions, with a special emphasis on colorectal cancer. To this objective, we will use different technological platforms (phosphoproteomics, gene expression profiling, DNA sequencing, gene copy number analysis) and various experimental settings (cell lines, ‘xenopatients’, and patient-derived cancer cell lines).

Maria Flavia Di Renzo MD Laboratory of Cancer Genetics [email protected] Rationale Intrinsic tumor suppression of oncogenes, although puzzling, is an actual self-defeating program that has evolved in cells to respond to the elevation in signal intensity accompaniyng oncogenic activation. This program does not confer a selective advantage and thus it is hidden in cancer cells, but it might be unleashed to commit cells to death. Results This laboratory has shown that the tyrosine kinase receptors elicit both survival and death signals and that the latter can be exploited to kill cancer cells. Using phosphoproteome and transcriptome approaches the laboratory has identified a number of transducers and effectors of the pro death activity of tyrosine kinase (TK) receptors. Among the transcriptional targets, some -such as the product of the CSE1L/CAS gene- play specific roles in ovarian cancer cells by killing and sparing the cells. Other signaling molecules have been identified, which are necessary for cancer cells to tolerate DNA damage and proliferative stress. Among these, the small heat shock protein of 27 KDa (HSP27) protects form the intrinsic oncosuppressive activities of TK oncogenes and can be inhibited to kill cancer cells where these oncogenes are activated. Projects and goals The goal of this Laboratory is to elucidate the mechanism of the death signalling elicited by the tyrosine kinase oncogenes in ovarian cancers to covert survival into death signals in these and other cancer cells. Therefore, first we aim at understanding whether the pro-death effect could be elicited by different TK oncogenes, such as MET, EGFR and HERII, activated by either over-expression or mutation. Then, mediators and effectors of the pro-death signaling of TK receptor should be identified. Subsequently, using an array of assays in vitro and in vivo, the role of the identified molecules should be validated to understand if these molecules might be targets for therapeutic intervention.

At the hierarchy’s apex there is a (small) subpopulation of ‘cancer stem cells’ (CSC) able to self-renew, namely to proliferate endlessly, and to relentlessly support tumor regeneration, growth, and dissemination. At the hierarchy’s base there is an ample subpopulation of cells that, unlike CSC, have limited proliferative ability, and tend to aberrantly differentiate and die. This hierarchical model implies that, to cure the tumor, CSC must be eradicated. This is a difficult task, because CSC are often inherently resistant to therapies that so far have been successful against the hierarchical basis of tumor cells. Results We showed that tumor cells resist to therapies that damage DNA through activation of the Met oncogene. The latter encodes the tyrosine-kinase receptor for HGF and controls ‘invasive growth’, a process featuring cell protection against adverse microenvironmental conditions. In tumor cells that underwent radiotherapy, Met is activated by molecular mechanisms that monitor DNA damage (such as ATM protein) and activate a transcription factor (NF-kB), responsible for a defense program against damage. This program includes activation of Met, which promotes survival and ‘adaptive resistance’ against irradiation. Thus Met mediates a molecular mechanism of radioresistance, and provided a rationale to combine radiotherapy with drugs targeting the oncogene. Projects and goals In CSC derived from colorectal cancer, glioblastomas and other tumor models, we plan (i) to study whether Met controls the CSC ability to self-renew and to disseminate from primary tumors, that is to form metastasis; (ii) to verify whether the Met oncogene mediates resistance to irradiation and other DNA damaging agents; (iii) to study whether specific agents targeting Met, such as tyrosin-kinase inhibitors or monoclonal antibodies, alone or in association with other conventional or targeted therapies, can help to eradicate CSC.

Integrative genomics evaluates systematically, on large datasets, multiple kinds of gene alterations, at the DNA, RNA and microRNA level. In this way it is possible to study the regulatory networks of cancer and to identify the key alterations that drive tumor progression and response or resistance to specific treatments. Results We have defined molecular signatures in colorectal cancer (CRC), associated to the involvement of the MET oncogene in hemostasis alterations and in resistance to radiotherapy. We have characterized the MET-driven invasive growth genetic program in embryonal liver progenitors, and found that it is associated to metastatic propensity of hepatocellular cancinoma, cholangiocarcinoma and other cancers. Through expression profiling of white blood cells we have defined transcriptional signatures associated with germline mutation of RAS pathway genes. We have identified a drug, already under clinical testing, effective on about 10% of CRC, including BRAF and KRAS mutatants. Finally, we have identified the MACC1 gene as a positive predictor of early relapse in patients operated for liver-metastatic CRC. Projects and goals Identify and experimentally validate new therapeutic and prognostic determinants of colorectal cancer. We aim (i) to complete preclinical validation, in patient-derived xenograft tumors, of the efficacy of a new therapy targeted on the ubiquitin ligase pathway, (ii) to validate in vitro and in vivo the therapeutic relevance of a translocation potentially mediating resistance to EGFR-targeted treatments; (iii) to define therapeutic and prognostic relevance of aberrant mRNA/microRNA circuits in CRC subgroups; (iv) to define molecular signatures associated to sensitivity or resistance of rectal cancer to preoperative chemo-radiotherapy.

Federica Di Nicolantonio PhD Laboratory of Pharmacogenomics [email protected] Rationale Several approved conventional chemotherapeutic agents were originally designed to act on cell replication or fundamental metabolic patways of cancer cells. The mechanisms underlying the sensitivity of individual tumors to chemotherapy have not yet been elucidated. Results The presence of BRAF oncogenic mutations is associated with increased sensitivity to chemotherapeutic agents capable of inhibiting the proteasome. The pharmacogenomic relationship between oncogenic BRAF and proteasome inhibitors has been validated in several BRAF mutant colorectal cancer cell lines, as well as in xenograft models. Mechanistically, we speculate that BRAF-mutant cells may experience a non-oncogenic addiction to the proteasome function because the protein degradation mediated by the ubiquitin-proteasome system is needed to counterbalance the proteotoxic stress induced by the mutant protein. Projects and goals Unveil and functionally validate synthetic lethal interactions that encompass conventional chemotherapy with tumor epigenetic and genetic variants.

J Clin Oncol. 2014, 32:579-86 Alberto Bardelli PhD Laboratory of Molecular Genetics [email protected] Rationale The findings that cancer is a genetic disease and that the combination of molecular alterations in the genome of somatic cells is the engine of tumor progression have revolutionized oncology and lead to the definition of the idea of precision medicine in oncology. This project has been conceived to develop this research topic using colorectal cancer (CRC) as experimental model, to identify new therapies that target the genetic alterations from which tumors are dependent for their growth. Results Over the past five years, our research program translated into the first case of personalized treatment in metastatic colorectal cancer. At the moment, the treatment of this disease is conducted by targeted therapy with monoclonal antibodies (moAbs) that identify the EGFR receptor. However, these drugs provide a significant clinical advantage in only 10% of patients. Using samples from the clinic and innovative cell models, we showed that the CRC having molecular alterations at the level of the effectors downstream EGFR (such as KRAS, NRAS, BRAF) are resistant to treatment with antibodies directed against EGFR. In parallel to the definition of tissue biomarkers, we developed a cutting-edge technology that allows to identify oncogenic alterations in the DNA released by neoplastic cells in the flow of blood. Projects and goals Our future goals concern the identification of new personalized treatments for colorectal cancer through the study of the association between the molecular characteristics of the single patients and the response/resistance to treatment in preclinical models. With some coordination activities, our group participates in clinical trials in which the hypotheses we put forward by using preclinical models are experimentally evaluated in coorts of patients. Within these studies, the response to treatment is also evaluated drawing real-time the molecular profile of the patient through the liquid biopsy approach described before. Team Sabrina Arena, Sebastian Hobor, Simona Lamba, Luca Lazzari, Sandra Misale, Mariangela Russo, Beth Van Emburgh, Giulia Siravegna, Carlotta Cancelliere, Benedetta Mussolin From Molecular Biology to “Precision Medicine” | 31 Antibody gene transfer for ‘active’ targeted cancer immunotherapy Elisa Vigna PhD Laboratory of Gene Transfer [email protected] Rationale Clinical evidence indicates that the MET oncogene plays a role in progression of cancer toward metastasis and/or resistance to targeted therapies. While mutations are rare, the common mechanism of MET activation is overexpression, either by gene amplification (‘addiction’) or transcriptional activation (‘expedience’). In both instances ligand-independent kinase activation plays the major role in sustaining the transformed phenotype. Currently available MET antibodies are directed against the receptor binding site, behaving essentially as ligand (HGF) antagonist, and are ineffective in ligand-independent activation. Results The monovalent chimeric MV-DN30 antibody, delivered as purified protein, binds the fourth IPT extracellular domain and induces proteolytic cleavage of MET, dramatically inhibiting downstream signaling pathways, in both absence or presence of ligand. As an inventive approach, Mv-DN30 was delivered by ‘gene therapy’ driven by a second generation bidirectional lentiviral vector. In vitro, the antibody displayed a strong inhibition of ligandindependent invasive growth of MET ‘addicted’ cancer lines, and –notably- of primary cells from a MET amplified gastric ca. patient. In vivo the antibody strongly impaired the growth of a panel of MET ‘addicted’ human cancer lines, xenotransplanted in nude mice lacking HGF. In patient-derived RAS wt colorectal cancer xenografts, MET amplification was found to correlate with resistance to anti EGFR therapy. By the gene therapy approach, direct Mv-DN30 gene transfer in nude mice, intra-tumor or systemic, was followed by a therapeutic response of MET addicted human glioblastomas and lung carcinomas.

Results We have been studying the mechanisms that provoke resistance to targeted therapies against MET and EGFR receptors. We have recently observed that Met amplification can provoke resistance to anti-EGFR therapies in colorectal cancer; simultaneous inhibition of Met and EGFR is able to reactivate the response. We have also identified molecular mechanisms that make tumor cells resistant to the treatment with kinase MET inhibitors or with specific monoclonal antibodies.

From Molecular Biology to “Precision Medicine” | 33 34 | From Molecular Biology to “Precision Medicine” Research Topic 3 Investigational Clinical Oncology Over the past few years, the improved knowledge on the biological, genetic and molecular heterogeneity of tumors, together with the development of pharmacological technologies, allowed the identification of molecular targets for novel therapeutic strategies. This fast process led to the overall reconsideration of classical approaches to clinical oncology, traditionally oriented toward design of treatment cancers irrespectively from the biological and genetic peculiarities that can make each tumor a pathology on its own. The identification of patients likely to respond to specific treatments according to the presence of relevant molecular targets (personalized medicine) and based on the expression of potential markers of sensitivity or resistance, needs clinical studies that result from a constant and productive interaction among the professionals with a significant background in the various disciplines.The goal of the “Investigational Clinical Oncology” team is to increase the therapeutic index of molecular targeted drugs, by the identification and clinical validation of biomarkers of sensitivity/ resistance. This goal is pursued through the development of research programs aimed at designing hypothesisdriven clinical trials that directly derive from the Institute biological, genetic and molecular research. In order for these tasks to be implemented, an ad-hoc organizational structure favours the interchange and the synergy among preclinical researchers, oncologists and pharmaceutical companies – which are the potential providers of new drugs for clinical trials. Another INCO’s goal will be the promotion of a clinical research culture based on the knowledge of molecular biology and tumor genetics, and particularly of the mechanisms of sensitivity or resistance to molecular targeted drugs. This organization is instrumental to the referral of patients for admission into top-priority clinical trials. Research Topic 3 is focused on: 3.0 Rational design of clinical trials for targeted drugs. Investigational Clinical Oncology | 35 HERACLES and ARES: trials for the ‘Precision Medicine’ of Cancer. Silvia Marsoni MD Unit of Clinical Trials [email protected] Rationale Understanding of the cancer genome is driving the transition from a morphology-based to a genetics-based cancer taxonomy. For many targeted treatments the molecular features of a patient’s cancer can predict the likelihood of clinical benefit, independently from the organ of origin. At the same time, point-of-care companion diagnostics are becoming available that will make personalized treatment a reality. This is the so called ‘precision medicine’. Practicing precision medicine requires the overcoming of a number of key hurdles, both scientific and nonscientific. Results In the last two years we focused on the AIRC 5x1000 project ‘Targeting resistances to EGFR directed therapies in colorectal cancer’ and designed and conducted our first precision trial aimed at treating HER2 amplified metastatic colorectal (mCRC) patients. Researchers from the Institute recently demonstrated that HER2 amplification drives primary resistance to EGFR directed treatment mCRC patients, and that HER2-amplified tumours in mCRC patient-derived xenografts (xenopatients) showed tumour shrinkage when treated with lapatinib and trastuzumab in combination. We therefore designed HERACLES, a therapeutic trial of targeted therapy without chemotherapy, to establish the efficacy of lapatinib and trastuzumab in HER2 amplified mCRC patients. Preliminary results in the clinical trial suggest that only specific amplification profiles drive responses in pluri-chemotherapy and cetuximab resistant mCRC patients. Projects and goals We will continue to design ‘molecular-driven’ proofs of concept trials in markers–enriched subpopulations suggested by the in-vitro and in vivo results in the traslational programs of the Institute. Through several multiinstitutionals longitudinal studies we are building a storehouse of molecularly and clinically annotated tumors samples that will allow researchers to mine for new targets or ways to improve existing drugs, and clinician to select patients to be ‘funneled’ into target-therapy treatments tailored to their tumor molecular landscape. PROFILING, the prototype of these studies now includes around 700 cases. Team Antonella Balsamo, Cosimo Martino, Marilì Vitiello 36 | Investigational Clinical Oncology The CTU goal is to make precision medicine possible in the Institute, by shaping the clinical validation path of new putative targets found in the Institute preclinical programs.

The combination of drugs targeting HER2 with conventional chemotherapy has proven successful in improving the prognosis of women whose breast cancer carries this abnormality. Newer HER2 targeting treatments are more and more effective, but often associated with increased complexity and costs. The identification of biomarker of optimal response to HER2-targeting agents would allow, in selected cases, simplified treatments and the omission of conventional chemotherapy without compromising efficacy. Results HER2-positive breast cancer patients whose tumors co-express high levels of the estrogen receptor (ER) may be less sensitive to the monoclonal antibody trastuzumab combined with chemotherapy. A subset of HER2-positive breast cancer patients could be spared cytotoxic chemotherapy. HER2-positive cancers of women achieving long-lasting benefits from antiHER2 treatments without chemotherapy in the randomized phase II HERLAP trial, shared common molecular features. This allowed the identification of candidate biomarkers of particular sensitivity to anti–HER2 therapy. Projects and goals (i) To confirm the candidate biomarkers identified in the HERLAP study in the ongoing HERLAP2 study, a phase II, prospective, multi-Institutional trial where women will receive two anti-HER2 agents, trastuzumab and lapatinib, in combination as upfront treatment for HER2-positive metastatic breast cancer; (ii) to establish pre-clinical model to study mechanisms of resistance or susceptibility to anti HER2-treatments related to the candidate biomarkers that have been identified in the HERLAP and HERLAP2 clinical trials; (iii) to establish patient-derived xenograft (Xenopatients) of HER2-positive/ ER-positive and HER2-positive/ER-negative tumors to study strategies to circumvent resistance to molecularly targeted therapies. Team Sonia Capellero, Caterina Aversa, Elena Geuna, Rossella Martinello Investigational Clinical Oncology | 37 AGNOSTOS: Target Therapy and Cancer of unknown primary (CUP). Valentina Rossi MD Center for Metastasis of Unknown Primary Cancers (CUPs) [email protected] Rationale Cancer of unknown primary (CUP) is defined as metastatic cancer in the absence of a clinically detectable anatomically defined primary tumor site, after an adequate diagnostic evaluation. This condition defines a highly malignant syndrome which accounts for up to 6% of the whole cancer population and - at the present - still lacking appropriate therapies. While the majority of CUP related studies are focused on how best track down the putative cancer of origin, the real enigma of this syndrome is related to its biological and genetic setting as supported by growing evidence suggesting that indeed the rationale for personalized targeted therapies is in the cancer cells genomic alteration, rather than in the tissue of origin. Results Given the highly aggressive metastatic phenotype of CUPs we focused on the Met oncogene, a key player of the ‘invasive growth program’, and recently demonstrated a five-time higher mutational incidence (15% vs 3% of unselected cancer population) in a cohort of about 50 CUP patients. Projects and goals The activity of the CUPs Center is part of AGNOSTOS, a larger program to optimize the diagnosis and the treatment of CUP patients at our Institute. AGNOSTOS includes a comprehensive diagnostic algorithm and a phase 2 trial in which patients, whose metastases harbor an ‘actionable’ molecular alteration including MET, will be treated with the accordingly appropriate targeted drug. Treatment outcome will be monitored with both traditional methods and BEAMing, a ‘liquid biopsy’ technique that uses the putative ‘actionable’ target as a marker of therapeutic success. In addition, as part of this program, the tumor material of CUPs, which harbor specific genetic lesions, will be implanted in immune-compromised mice to establish humanmouse (Xenopatients) models of CUPs for preclinical studies. Team Giulia Maria Stella, Tiziana Venesio, Claudio Valizia, Patrizia Morbini 38 | Investigational Clinical Oncology The project aims to build a genomic profile of CUPs, focusing on MET and selected oncogenes known to be frequently mutated in cancer.

Expert Opin Investig Drugs. 2010, 19:1381-94 Research Topic 4: Applied Clinical Research The the ultimate task of the Institute is the development of clinical research integrated with health assistance, also through nationally- and internationally-controlled clinical trials. With the introduction of molecular therapies, it has been understud that a specific disease can have different characteristics that need different therapies. Treatments are therefore oriented toward personalized therapy, which needs a very sophisticated molecular diagnostics armamentarium that the Institute is able to provide. Ongoing clinical research integrates the Divisions, the Laboratories and the Facilities, in order to allow the synergy among different highly-specialized technologies and complementary, diagnostic and therapeutic know-how. The research goal is the progress of science, but the figure and the well-being of the patient are an absolute priority. The participation in the experimental protocols is voluntary and is suggested to patients according to the biological and clinical characteristics of the disease. The Ethics Committee of IRCCS-FPO guarantees that patients receive only treatments having solid scientific bases and that they are monitored with the most serious attention. In compliance with the Declaration of Helsinki, the patient who does not wish to participate in a trial receives the best “standard” therapy. Oncologists, surgeons, radiologists and radiotherapists cooperate with researchers to design clinical trials based on molecular data, intended to verify and generate hypotheses. In order to make this cooperation productive, the Institute manages a daily net of interactions involving formal aspects (seminars and meetings), training (refresher courses and lessons) and operational efforts (contacts with the pharmaceutical companies, regulatory and management instruments). Clinical Research is the last and more important haven to improve the assistance to cancer patients, to increase their life expectancy and to provide them with the most appropriate, safe and effective therapeutic approach according to the genetic characteristics of their own tumor. The controlled clinical Protocol is the final product of the overall work of a multidisciplinary group composed of basic researchers, oncologists, surgeons, pathologists, pharmacologists, radiologists and nuclear medicine doctors, biostatistics and bioinformatics scientists, research healthcare assistants, data managers and legal experts. Below the main projects of the Applied Clinical Research are listed, followed by the table of Controlled Clinical Trials. Research Topic 4 concerns: 4.1. Pathology of colorectal cancer onset and progression 4.2. Development of new therapeutic strategies 4.3. New approaches to surgical oncology 4.4. Laboratory Medicine, Imaging and Radiotherapy Applied Clinical Research | 39 Stochastic modelling of colorectal tumorigenesis. Mauro Risio MD Unit of Pathology [email protected] Rationale Knowledge of the biological machineries sustaining the progression rates and times of Colorectal Adenomas will be crucial to refine the natural history assumptions in Colorectal Cancer (CRC) screening modeling. The rate for evolution is driven by genetic events that promote tumor progression: in the large majority of cases of sporadic CRC, genetic instability occurs at chromosomal level (CIN) and gain in the long arm of chromosome 20 is one of the most frequent chromosomal aberration observed in CRC. Narrowing down the gain region, several studies aiming to identify candidate genes for tumor progression on 20q have pinpointed Aurora Kinase A (AURKA), a member of cell-cycle regulating serine-threonine kinases family and an important regulatory protein of the mitotic process. An association between aberrant expression of AURKA and chromosomal instability has been assumed because accurate regulation of mitotic spindle formation is crucial for proper chromosome segregation. Results Morphological features of dysplasia have been demonstrated to be inadequate when used in colorectal cancer screening programmes. It has been proven that a unique histologic feature, tumour budding is a reliable marker of the metastatic potential of cancerised adenomas and an overall fair level of diagnostic agreement has been demonstrated in T1 CRCr when using quantitative and selective methods for its measurement. Projects and goals The research aims to unravel genetic and histological markers of evolving CRC precursors: (i) To explore the role of multipolar mitoses and of “catastrophic mitoses” (caspase2-mediated intramitotic apoptosis) as histological markers of progression; (ii) to assess the involvement of AURKA gene in the various steps of CRC evolution; (iii) to evaluate the profile of expression of key molecules, (HIF-1alpha, VEGF, GLUT1, CA IX, CA XII), in cancerised colorectal adenomas.

Francesco Leone MD Unit for the Study of Tumors of the Gastrointestinal Tract [email protected] Rationale Biliary tract carcinoma has generally poor prognosis. Treatment options are weak and the expectation of long-term survival is extremely limited. A better understanding of the pathogenetic mechanisms could identify novel therapeutic strategies. Results We have identified, some potential molecular targets including SRC and EGFR. On the basis of these observations, we have designed and coordinated a multicenter clinical trial designed to explore the activity of a combination of chemotherapy (gemcitabine + oxaliplatin) with the monoclonal antibody panitumumab in patients with unresectable biliary carcinoma and KRAS wild-type status. The primary objective of the study is to demonstrate that the combination of chemotherapy and EGFR antibodies it gets a disease control superior to chemotherapy alone. Projects and goals Identify new potential therapeutic targets for cancer of the biliary tract in preclinical studies and develop, based on the results obtained, innovative clinical trials. Team Federica Colombi, Renato Ferraris, Donatella Arino, Caterina Peraldo Neia Applied Clinical Research | 41 Cell therapy for metastatic tumors Fabrizio Carnevale-Schianca MD Unit of Cell Therapy [email protected] Rationale Despite important progresses reached by conventional treatments (e.g. chemotherapy, radiotherapy), and the recent enthusiasms brought by molecular targeted therapies, many types of metastatic tumors remain incurable. Cell therapy is still considered a promising approach, with potential positive synergism with recent molecular targeted therapies. The potential of cell therapy has been demonstrated by hematopoietic cell transplant (HCT) in hematologic malignancies, by new immunomodulatory agents (Ipilimumab; anti-PD1) against some solid tumors and by adoptive immunotherapy using ex-vivo expanded anti-tumor T lymphocytes. Results Among others, we demonstrated that HCT may be considered an ideal platform to support further antitumor immunologic interventions. Results were produced within single and multi-center trials in the settings of Multiple Myeloma, Colorectal Cancer and other solid tumors. Projects and goals (i) investigation and modulation of immunologic mechanisms underlying the GVT and GVHD events, (ii) definition and clinical application of adoptive immunotherapies against metastatic tumors. The program includes: (a) preclinical and clinical evaluation of the immunomodulatory potential of Cyclofosfamide in the post HCT setting. (b) Evaluation of the immunereconstitution. (c) Induction of T lymphocytes against tumor associated antigens, and (d) generation and adoptive infusion of Cytokine-induced killer cells against mesenchymal tumors and melanoma.

Ann Oncol 2012, 23:508-16 Giovanni Grignani MD Unit for Investigation and Therapy of Sarcomas [email protected] Rationale According to genetic alterations, we now identify sarcomas so called genetically simple (i.e.: diseases characterized by a genetic alteration clearly related to the tumor pathogenesis) and complex (i.e.: tumors carrying multiple genetic defects none of which is clearly pathogenetic or pathognomic). Within this scenario, translational research has been focused on the discovery of molecular mechanisms endowed with potential therapeutic implications. Results (i) We have joined international clinical trials on new chemotherapeutic drugs (Trabectedin, TH-302, Palifosfamide, Eribulin) to explore the possibility to overcome the well-known sarcoma refractoriness; (ii) we have identified the role of ERK1 and 2 in osteosarcoma and coordinated a phase II trial on the activity of the multikinase inhibitor ‘Sorafenib’ in the treatment of relapsed and unresectable disease; (iii) we have completed a phase II study showing the activity of ‘imatinib’ in advanced chordoma after failure of standard therapies; (iv) we have shown the efficacy of ‘Pazopanib’ in advanced soft tissue sarcomas after failure of standard therapies. Projects and goals (i) From preclinical data showing that mTOR pathway is activated during Sorafenib treatment of relapsed osteosarcoma, we are running a phase II study in relapsed and unresectable osteosarcoma, exploring the combination of ‘Sorafenib with Everolimus’; (ii) we are involved in a prospective phase II clinical study on the monoclonal antibody ‘MorAb’ in refractory soft tissue sarcomas; (iii) we are developing a preclinical model of adoptive immunotherapy to integrate both target and chemotherapy.

Giorgio Valabrega MD Unit for Gynecological Cancers [email protected] Rationale Although multimodal treatments improved clinical outcome of ovarian cancer, the cure rate has not changed significantly. After surgery, approximately 70% of patients benefit from first-line chemotherapy (platinum compounds), the others being intrinsically refractory. In addition, approximately 70% of patients develop a secondary resistance. Therefore, a critical problem is the management of primary and acquired resistance to platinum-based drugs. There are promising targeted therapies (eg PARP inhibitors, MEK inhibitors, inhibitors of VEGFRs), that must be adapted to the specific genetic and epigenetic landscape of each ovarian cancer. Results Collection, in progress, of vital tumor material from patients with ovarian cancer surgery. Part of this material is systematically implanted into immunocompromised mice (Xenopatients) to establish in vivo models for preclinical studies. Projects and goals Establishment of human-mouse models (Xenopatients) of platinum refractory/resistant ovarian carcinomas, to identify biomarkers of sensitivity /resistance to standard chemotherapy and targeted therapies.

Team Massimo Battistella Applied Clinical Research | 45 Irreversible electroporation as treatment of pancreatic adenocarcinoma. Michele De Simone MD Unit of Surgical Oncology [email protected] Rationale 80% of pancreactic cancer patients are not manageable by surgery, because of metastatic disease (40%) or local major vessels involvement (40%). In recent years, many loco-regional therapies have been studied and most of them elicit tumor cell ablation by mean of thermal injury (Thermoablation). However these procedures are not free for side effects. Irreversible Electroporation (IRE) can lead to a selective neoplastic tissue destruction sparing normal tissues. IRE is based on short and low-voltage electric pulses that causes nanopores in the double layer of phospholipids in the cellular membrane. Results Preclinical studies on animal models showed that IRE doesn’t damage structures of hepatic hilum, coeliac trunk and duodenum. Similarly human studies have demonstrated that IRE is safe towards bile ducts, vessels, urethra, spermatic ducts and neurovascular structures. Moreover ongoing clinical trials in not resectable locally advanced pancreatic adenocarcinomas are endwed with promising results. Projects and goals (i) Evaluating feasibility and safety of IRE, in organs other than pancreas (liver); (ii) evaluating overall survival and recurrence rate after IRE for not resectable advanced pancreatic adenocarcinoma; (iii) Evaluating capacity of IRE in downsizing/downstaging in not resectable pancreatic neoplasia and rate of patients becoming suitable for surgery.

One of the main objectives of breast cancer treatment is the introduction of more effective ways to integrate the advancements in imaging, surgery and radiotherapy. Results (i) Treatment of the primary tumor: we experimented magnetic resonance imaging for the pre-operative staging of breast cancer, accelerated partial breast radiotherapy and new techniques for mastectomy with preservation of the whole skin envelope; (ii) treatment of regional lymph nodes: we tested several algorithms to predict the involvement of non-sentinel lymphnodes, the effect of omitting axillary dissection on the indication to adjuvant therapies and the technique of “axillary reverse mapping” to spare the lymphatic channels of the arm. Projects and goals (i) Development of new strategies for selecting patients at increased risk of local-regional recurrence; (ii) Validation of the safety of new surgical approaches; (iii) Implementation of platforms of “pre-surgical therapy” for assessing innovative drugs.

Applied Clinical Research | 47 Identification of new markers of thromboembolic events Antonino Sottile MD Laboratory Medicine [email protected] Rationale Recent studies showed that apheresis procedures worsen the prothrombotic state of patients, even leading to the chance that, during the reinfusion of the cells, thrombotic events could happen. In particular, it is essential to have new analytes, more sensitive and specific, suitable for early diagnosis and patients monitoring. Results The laboratory is engaged in the identification of new markers of neoplastic pathology by using the most innovative measurement techniques with cutting-edge instrumentation. We use a new tests for the determination of fecal occult blood, to identify the early metabolic alterations provoked by colon cancer. Projects and goals For cancer patients, venous thromboembolism (VTE) is the most frequent and the second cause of death. The prothrombotic state is worsened by chemotherapy, surgery, central venous catheter insertion (CVC) and, more in general, by invasive therapies to which the patients are often subjected. A percentage of patients between 0.3% and 28.3% show venous thromboembolism clinically, while a percentage of patients between 27% and 66% show it after x-ray examination. Our project aims ad identifying new laboratory tests allowing the selections of patients who may have more chances to develop venous thrommboembolism.

Daniele Regge MD Image and Data Processing Laboratory (IDP) [email protected] Rationale The more variables are provided by Computed Tomography (CT) and Magnetic Resonance Imaging (MRI), the more time-consuming it is even for the experienced reader to integrate all the available information into one reliable final report. To deal with these complex problems CAD systems have been introduced to provide a list of disease suspicious areas as final output. The CAD systems automatically highlight suspicious regions on a parametric color-coded map representing the cancer probability on a voxel-wise basis. Results The IDP Lab developed CAD systems for the 1) early diagnosis of Colorectal Cancer on CT-colonography (CTC); 2) diagnosis of breast cancer on MR images; 3) diagnosis of prostate cancer on multiparametric MR exams with endorectal coil. The perfomances of the CTC-CAD have been assessed on a large cohort of asymptomatic individuals. Projects and goals The IDP Lab is completing the development of a CAD system for prostate cancer detection. Future efforts will be focused on the reduction of false positive prompts, through the refinement of mathematical algorithms, and the implementation of a CAD system aimed to provide a reliable estimate of prostate tumour aggressiveness, especially in those cases characterized by indolent clinical course. Imaging data will be integrated with molecular information, using statistical classification methods.

Rationale Aim of the project is to define a model to optimize the use of radiotherapy using genomics information and “theragnostic” data, in order to personalize the treatment. The IMRT techniques (Intensity Modulated Radiation Therapy), SBRT (Stereo Body Radiotherapy) and IGRT (Image Guided Radiotherapy) give us the opportunity to use high doses, perfectly “sculpted” on the basis of the areas that are going to be treated.

European Journal of Nuclear Medicine. 2013, 40:470-4 Teresio Varetto MD Unit of Nuclear Medicine [email protected] Rationale Molecular imaging with nuclear medicine techniques and particularly with Positron Emission Tomography (PET) is a rapidly evolving field of imaging science by which molecular events are non-invasively visualized, characterized and measured in living cells, animals and humans. With PET imaging it is now possible to non-invasively evaluate various important cancer features in clinical patients, such as metabolism, cellular proliferation, tumor hypoxia, tumor angiogenesis and receptor expression. In some cases, it is also possible to assess the expression of receptor proteins on the cell surface. Results We demonstrated in preclinical models, that it is possible to assess –by PET imaging- the expression of genes involved in tumor development, growth and invasion (oncogenes). In particular we developed a technology based on the use of monoclonal antibodies labeled with Indium and Zirconium radioactive isotopes. Projects and goals Our future goals will be to develop PET and SPECT “molecular imaging” techniques with radiolabeled monoclonal antibodies targeting proteins encoded by oncogenes. And to assess their value in predicting response to therapy and in targeting resistance to the new molecular therapies.

Massimo Aglietta MD Medical Oncology [email protected] Rationale The possibility of identifying molecular alterations potentially involved in tumor progression is the mainstay of personalized antitumor therapy. In epithelial and mesenchimal neoplasias, through molecular analysis of fresh tumor sample or by studying ex vivo models (including xenopatients) we have been able to formulate hypothesis and build prospective clinical trials to test them. Results In epithelial neoplasias we have been looking for gene alterations predictive of response to anti EGF therapies. (i) In mammary carcinoma during the HERLAP study (see also 3.2) we have been collecting tumor samples of patients treated with different anti HER-2 therapies. A gene profiling predictive of an increased sensitivity to anti HER-2 treatment has been identified. Since resistance invariably develops, further analyses are in progress to identify molecular changes occurring at this stage. (ii) In preclinical models of biliary tract cancer we have identified EGFR as a potential therapeutic target in patients with K-ras WT tumors. A multicenter randomized phase II study has been (VECTIBIL see also 4.2.1) conducted. (iii) Osteosarcoma is a mesenchimal neoplasia with several molecular alterations potentially involved in the neoplastic progression. In preclinical models we have provided evidence of a pivotal role of MAP-K activations in tumor growth. On these bases we have performed a phase II study in metastatic patients resistant to chemotherapy to test the activity of Sorafenib, a multitarget inhibitor of the MAP-K pathway. We have demonstrated a significant antitumor activity. However secondary resistance associated to activation of m-TOR pathway develops. Thus we we are performing a second phase II study (SERIO, see also 4.2.3) to test if the m-TOR inhibitor Everolimus enhances the activity of Sorafenib. Accrual is completed. Projects and goals Extensive molecular analysis of tumor tissue derived from clinical studies to try to understand the mechanism beyond primary and secondary resistance to target therapies.

He directs health services and is responsible for hygiene and prevention (hospital infection control and environmental hygiene). The clinical service office monitors the appropriateness of admissions, the hospital stay lenghts, the average weight of the so called ‘case mix’ and supervise the waiting list. He coordinates with the Operation Department the proper use of spaces and the timely flow of goods and services. The clinical service office: (i) he is in charge of the control of the fulfillement of results obtained within the assigned objectives; (ii) coordinates the facilities of the hospital including the provision of appropriate protocols; (iii) defines strategies and guidelines for the extraordinary and/or urgent intervention; (iv) advices on building planning about further hospital expansion; (v) Supervises the ‘conventional’ agreements and the related reports with the University Clinical Services | 55 56 | Grant Office and Research Administration Grant Office and Research Administration Daniela Gramaglia PhD [email protected] Michelina Bruno Ms [email protected] The Scientific Director’ Office supervises, coordinates and manages the basic, translational and clinical scientific research in the Institute. To this end, the Grant Office provides the scientific support for institute research activities and acts as a liaison between researchers and funding agencies. The Grant Office assists researchers in identifying appropriate research funding opportunities, centralizing all information on major national and international, private or public, agencies, foundations, and institutions that support research. Whenever a call for a research grant is issued, it is advertised throughout the Institute by e-mail. The Grant Office provides assistance to researchers in the preparation of applications, in the drawing up of the budget together with the administrative office of the Institute -, in completing the application forms and interpreting the regulations of the granting agencies, assuring compliance with the sponsors’ policies and requirements. In case of successful outcome of the proposals, the Grant Office helps in preparing reports, consortium agreements with collaborating institutions, and renewal forms. Grant Office and Research Administration | 57 CORE FACILITIES Entering into new scientific challenges and aiming for breakthroughs require adapted technologies and a research strategy. Candiolo Cancer Institute therefore pays extra attention to developing and attracting advanced technologies in order to allow researchers to perform cutting-edge science in cancer research. The Oncogenomics Center (OGC) Genetic alterations in tumors are predictors of response or resistance to targeted therapies, and their identification is mandatory for molecular diagnosis and therapeutic decisions. Technological advances in experimental and informatics methodologies over the past 10 years have made possible the characterization of cancer genomes. OGC is the supportive infrastructure for all genomic studies, including transcriptional, mutational and gene copy number analyses of cells, tissues and liquid biopsies. Dedicated personnel and instrumentation are devoted to provide services for qRT-PCR studies, Sanger and Next Generation Sequencing experiments, Gene Expression Array analyses and BEAMing tests. The Bioinformatics Center (BIC) Modern research in cancer biology implies the collection of extensive data from experimental models concerning specific genetic lesions that drive cancer initiation and progression. Such data will include, for example, large sets of expression transcript profiling, comparative genomic hybridization profiling, whole genome sequencing, immunohistochemical data, and morphologic data that will be peculiar to each specific tumor. Thus, a bioinformatics platform for integrated data tracking and normalization is critical to the successful realization of this endeavor. BIC comprises a web-based bioinformatics platform (Laboratory Assistant Suite, LAS; http://devircc.polito.it/ wordpress/)that assists biomedical researchers in multiple activities, which range from tracking data generation and execution of standard operating procedures (SOPs) to management of multidimensional molecular profiles and complex data analysis and integration, by managing multiple independent databases that are linked together in an interconnected network (‘oncogrid’). The Oncology Imaging Center (OIC) Basic research in disciptopics such as cell biology, molecular genetics and developmental biology has provided invaluable insights into the regulatory circuits that govern cancer onset and progression. Within this context, we postulate that imaging studies in cell topics and tissues will parallel genomic analyses and in vivo experimentation, constituting an integrative platform for rapid testing of emerging research directions. OIC technologies include comprehensive microscopic imaging systems, such as confocal microscopes, live-cell devices for real-time monitoring of cellular behaviors, and high-throughput platforms for functional screens. 58 | Core Facilities The Flow Cytometry Center (FLOCC) Increasing evidence shows that tumors are structured in a hierarchical form, with a majority of cells undergoing aberrant differentiation but retaining a proliferative capacity limited over time, and a tiny fraction of cancer stem cells (CSCs) or cancer-initiating cells (CICs) that are able to self-renew and continuously regenerate or add to the tumor. FLOCC enables researchers to take advantage of state-of-the-art FACS (fluorescence-activated cell sorter) technologies and dedicated personnel with highly specialized technical skills in order to tackle these issues, by allowing analysis and prospective isolation of individual cancer cells within highly heterogeneous populations. series of human cancer specimens directly transplanted into mice (“xenopatients”). XEBB provides researchers with a collection of more than 400 liver metastases from colorectal cancer that have been systematically transplanted in immunocompromised mice to obtain more than 200 stable tumor topics (xenopatients), which are available for any kind of in vivo/ex vivo study. The Xenopatients’ Biobank (XEBB) Immortalized cancer cells exhibit a genetic drift, a biological compliance and phenotypic features different from original cancers in patients. Another drawback of such an approach is that the catalogue of currently available cell topics is inevitably finite, and possibly poor for some tumour types. Therefore, experiments with cell topics cannot recapitulate the wide heterogeneity of human malignancy that occurs among individuals on a population basis. One way to tackle this issue is to perform population-based in vivo studies by using large Pharmacodynamics and Pharmacokinetics Service The Pharmacodynamics and Pharmacokinetics Service is an autonomous facility within the Insitute of Candiolo devoted to the study of neoplastic diseases in preclinical models. The most significant activitiy of the Service is the “xenopatients” project, which provides for the molecular classification of the surgical samples taken from the patients and their propagation in vivo in immunocompromised mice. The Institute of Candiolo employs animal testing but, thanks to the deep feeling that moves the Institution and its researchers, it adjoins solid ethical behaviours. The goal is to improve the procedures prescribed by the current national and international regulations, through an Ethical Committee for Animal Experimentation.
